What is a SQG?

A SQG is a business or other non-residential generator of hazardous waste that:

  1. Never generates more than 220 lbs. (approx. 27 gals.) of hazardous wastes and/or not more than 2.2 lbs. (approx. 1 qt.) of certain extremely hazardous wastes per calendar month and never accumulates more than 2,200 lbs (approx. five 55 gallon drums) of hazardous waste, or 2.2 lbs. of certain extremely hazardous wastes onsite at any time.
  2. Designates (properly identifies) hazardous wastes according to WAC 173-303-070.
  3. Manages hazardous wastes in a way that does not pose a potential threat to human health or the environment.
  4. Disposes of hazardous wastes in accordance with the Dangerous Waste Regulations, Washington Administrative Code Chapter 173-303. This program is compliant with disposal regulations.

All of these provisions must be met or the business can become a fully regulated hazardous waste generator.

Questions?

Call: Business Waste Line 206-263-8899, toll free 800-325-6165, ext. 3-8899 Monday through Friday, 9 a.m. to 4 p.m., closed noon -1 p.m. and holidays. Call ahead to see if the facilities are operating before visiting.

Is my small business eligible for this program?

This program is for businesses that have small amounts of moderate risk hazardous waste (see Acceptable wastes) that are not enough to require a hazardous waste vendor.

This program is not for businesses that routinely generate hazardous waste and have regular pick-ups by a contracted vendor, or for businesses that generate extremely hazardous waste.

You must qualify as an SQG under the Washington State Dangerous Waste Regulations.

What will I need to do to bring my waste to one of the facilities?

All SQGs are required to fill out a Business Disposal Form with the name, address and phone number of the business, and a responsible contact person’s name. The customer will also list each hazardous waste and the amounts. Information must be printed legibly.

How do I get the Business Disposal Form?

Print and bring 2 completed copies – including the waste inventory section or call the Business Waste Line at 206-263-8899 during business hours and a form will be mailed to you.

One copy is for your records and we recommend keeping it for a minimum of five years. One copy will be kept by the facility staff. Save time by filling it out before arriving at the disposal facility. Forms are also available at the facilities.

May I hire a hauler to take my wastes to the facility?

No contract hauling is allowed to the facilities. Your waste must be brought to the site by the owner/manager or a direct employee of the company.

What will participation cost me?

There is no fee at the time of service; it is funded by a surcharge on garbage and sewer services. To participate, businesses are required to complete the Business Disposal Form.

How can I recycle unused materials I no longer need?

IMEX, the Industrial Materials Exchange, matches up waste generators with waste users.

Where can I take my hazardous waste during this project?

You may take hazardous waste to the sites listed below. For more details and directions to our facilities visit our web site, or call our Business Waste Line at 206-263-8899 during business hours.
